hello coastflyer,
thankyou for the interest.
just to answer a couple of your questions.
the safety system on the hydra is whats to be expected for 2010, the kite has a unique way of switching off power when you let go of the bar. but if you need to release the kite its just a matter of pulling the quick release on the chook loop. your leash attaches to the small ring on the chook loop itself. this flags the kite out to the front lines. check website for more pics.
water relaunch is easy. it doesnt pop out the water quite like a delta shape kite but it doesnt take much effort at all.
you can also reverse launch the hydra if it lands leading edge down by pulling the rear lines.
hope this helps.
cheers james
